The single-ended periodontal instrument of FIG. 7 being the same asFIGS. 2-6 or mirror images thereof. The single-ended periodontalinstrument of FIG. 14 being the same as FIGS. 9-13 or mirror imagesthereof.

The portions of the periodontal instrument shown in broken lines form nopart of the claimed design.

In the drawings, the portion of the periodontal instrument with acolored lower shank shown with solid black shading indicates acontrasting color to that of the remainder of the shank and to theworking end.

The periodontal instrument with a colored lower shank of the presentdesign may be an explorer, a scaler or a curet, as such terms areunderstood by dentists, dental practitioners and others of skill in themanufacture or use of periodontal instruments, since the configurationof the lower shank portions of such periodontal instruments aresubstantially the same. The periodontal instrument with a colored lowershank, may be a double ended instrument as shown in FIGS. 1 and 8 or theperiodontal instrument may be a single ended instrument as shown inFIGS. 7 and 14.

For clarity, the lower shank (or terminalshank) of the periodontal instrument is that portion of the shank belowthe working end and which extends toward the handle to the first bend inthe shank.
